ABSTRACT

The invention relates to novel 3-aryl-5-halogeno-pyrone derivatives of the formula (I) ##STR1## in which A, D, G, X, Y, Z and n are each as defined in the description, 
     to a plurality of processes and intermediates for their preparation and to their use as pesticides and herbicides.

This application is a 371 of PCT/E96/04475 filed Oct. 15, 1996.

The invention relates to novel 3-aryl-5-halogeno-pyrone derivatives, to a plurality of processes and intermediates for their preparation and to their use as pesticides and herbicides.

Certain phenyl-pyrone derivatives without substitution in the phenyl ring have already been disclosed (cf. A. M. Chirazi, T. Kappe and E. Ziegler, Arch. Pharm. 309, 558 (1976) and K.-H. Boltze and K. Heidenbluth, Chem. Ber. 91, 2849 (1958)), but a possible use as pesticides has not been mentioned for these compounds. Phenyl-pyrone derivatives with substitution in the phenyl ring having herbicidal, acaricidal and insecticidal properties are described in EP-A-588 137.

However, the efficacy and the spectrum of activity of these compounds is, in particular at low application rates and concentrations, not always entirely satisfactory. Moreover, the crop safety is frequently insufficient.

This invention, accordingly, provides novel compounds of the formula (I) ##STR2## in which X represents halogen, nitro, cyano, alkyl, alkenyl, alkoxy, alkenyloxy, alkylthio, alkylsulphinyl, alkylsulphonyl, halogenoalkyl, halogenoalkenyl, halogenoalkoxy, halogenoalkenyloxy or respectively optionally substituted phenyl, phenoxy, phenylthio, benzyloxy or benzylthio,

Z represents halogen, nitro, cyano, alkyl, alkenyl, alkoxy, alkenyloxy, halogenoalkyl, halogenoalkenyl, halogenoalkoxy or halogenoalkenyloxy,

n represents one of the numbers 0, 1, 2 or 3,

A represents halogen,

D represents hydrogen or represents an optionally substituted radical from the group consisting of alkyl, alkenyl, alkinyl, alkoxyalkyl, polyalkoxyalkyl, alkylthioalkyl, saturated or unsaturated cycloalkyl, saturated or unsaturated heterocyclyl, arylalkyl, aryl, hetarylalkyl and hetaryl and

R² represents respectively optionally halogen-substituted alkyl, alkenyl, alkoxyalkyl or polyalkoxyalkyl or represents respectively optionally substituted cycloalkyl, phenyl or benzyl,

R³, R⁴ and R⁵ independently of one another each represent respectively optionally halogen-substituted alkyl, alkoxy, alkylamino, dialkylamino, alkylthio, alkenylthio or cycloalkylthio or represent respectively optionally substituted phenyl, benzyl, phenoxy or phenylthio,

R⁶ and R⁷ independently of one another each represent hydrogen, represent respectively optionally halogen-substituted alkyl, cycloalkyl, alkenyl, alkoxy, alkoxyalkyl, represent respectively optionally substituted phenyl or benzyl, or, together with the linking nitrogen atom, form an optionally oxygen- or sulphur-containing cycle.

Depending inter alia on the nature of the substituents, the compounds of the formula (I) may be present as geometric and/or optical isomers or mixtures of isomers, in varying composition, which can, if appropriate, be separated in a customary manner. The present invention provides both the pure isomers and the isomer mixtures, their preparation and their use and compositions comprising them. Hereinbelow, for the sake of simplicity, reference is always made to compounds of the formula (I) although this includes both the pure compounds and, if appropriate, also mixtures having varying proportions of isomeric compounds.

Depending on the position of the substituent G, the compounds of the formula (I) may be present in the two isomeric forms of formulae (I)_(a) and (I)_(b) ##STR4## which is meant to be expressed by the dotted line in the formula (I).

The compounds of the formulae (I)_(a) and (I)_(b) may be present both as mixtures and in the form of their pure isomers. If appropriate, mixtures of the compounds of the formulae (I)_(a) and (I)_(b) may be separated by physical methods in a manner known per se, for example by chromatographic methods.

For the sake of clarity, hereinbelow only one of the possible isomers is given in each case. It is implied that the compounds may be present in the form of isomer mixtures or in the other isomeric form in question.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants and/or foam-formers.

If the extender used is water, it is also possible to employ for example organic solvents as auxiliary solvents. Essentially, suitable liquid solvents include: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol and their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water.

Suitable solid carriers are:

for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates, suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and protein hydrolysates; suitable dispersing agents are: for example lignin-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, and natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

The active compound according to the invention may be present in the form of its commercially available formulations and in the use forms prepared from these formulations, as a mixture with other active compounds, such as insecticides, attractants, sterilants, acaricides, nematicides, fungicides, growth regulators or herbicides.

Bristletails, such as Lepisma saccharina.

Industrial materials are to be understood as meaning, in the present context, non-live materials such as, preferably, synthetic materials, glues, sizes, paper and board, leather, wood and timber products, and paint.

The materials to be very particularly protected against attack by insects are wood and timber products.

Wood and timber products which can be protected by the composition according to the invention or mixtures comprising such a composition are to be understood as meaning, for example, construction timber, wooden beams, railway sleepers, bridge components, jetties, wooden vehicles, boxes, pallets, containers, telephone poles, wood lagging, windows and doors made of wood, plywood, particle board, joiner's articles, or wood products which, quite generally, are used in the construction of houses or in joinery.

The active compounds can be used as such, in the form of concentrates or generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersant and/or binder or fixative, water repellent, if appropriate desiccants and UV stabilizers and, if appropriate, colorants and pigments and other processing auxiliaries.

The insecticidal compositions or concentrates used for the protection of wood and wooden materials comprise the active compound according to the invention at a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of the compositions or concentrates employed depends on the species and the occurrence of the insects and on the medium. The optimum rate of application can be determined upon use in each case by test series. However, in general, it suffices to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be protected.

The solvent and/or diluent used is an organochemical solvent or solvent mixture and/or an oily or oil-type organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water and, if appropriate, an emulsifier and/or wetting agent.

Organochemical solvents which are preferably employed are oily or oil-type solvents having an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C. Substances which are used as such oily and oil-type solvents which have low volatility and are insoluble in water are suitable mineral oils or their aromatic fractions, or mineral-oil-containing solvent mixtures, preferably white spirit, petroleum and/or alkylbenzene.

Substances which are advantageously used are mineral oils with a boiling range of 170 to 220° C., white spirit with a boiling range of 170 to 220° C., spindle oil with a boiling range of 250 to 350° C., petroleum or aromatics of boiling range 160 to 280° C., essence of turpentine and the like.

In a preferred embodiment, liquid aliphatic hydrocarbons with a boiling range of 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons with a boiling range of 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are used.

The organic oily or oil-type solvents of low volatility having an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C., can be partially replaced by organochemical solvents of high or medium volatility, with the proviso that the solvent mixture also has an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

In a preferred embodiment, part of the organochemical solvent or solvent mixture is replaced or an aliphatic polar organochemical solvent or solvent mixture. Substances which are preferably used are aliphatic organochemical solvents having hydroxyl and/or ester and/or ether groups, such as, for example, glycol ether, esters and the like.

The organochemical binders used within the scope of the present invention are the synthetic resins and/or binding drying oils which are known per se and can be diluted with water and/or are soluble or dispersible or emulsifiable in the organochemical solvents employed, in particular binders composed of, or comprising, an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenol resin, hydrocarbon resin, such as indene/coumarone resin, silicone resin, drying vegetable and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Up to 10% by weight of bitumen or bituminous substances can also be used as binders. In addition, colorants, pigments, water repellents, odour-masking substances and inhibitors or anticorrosives which are known per se and the like can also be employed.

The composition or the concentrate preferably comprises, in accordance with the invention, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil as the organochemical binder. Preferably used according to the invention are alkyd resins with an oil content of over 45% by weight, preferably 50 to 68% by weight.

All or some of the abovementioned binder can be replaced by a fixative (mixture) or a plasticizer (mixture). These additives are intended to prevent volatilization of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of binder employed).

The plasticizers are from the chemical classes of the phthalic esters, such as dibutyl phthalate, dioctyl phthalate or benzylbutyl phthalate, the phosphoric esters, such as tributyl phosphate, the adipic esters, such as di-(2-ethylhexyl) adipate, the stearates, such as butyl stearate or amyl stearate, the oleates, such as butyl oleate, the glycerol ethers or relatively high-molecular-weight glycol ethers, glycerol esters and p-toluenesulphonic esters.

Fixatives are chemically based on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether, or ketones, such as benzophenone or ethylene benzophenone.

Also particularly suitable as a solvent or diluent is water, if appropriate as a mixture with one or more of the abovementioned organochemical solvents or diluents, emulsifiers and dispersants.

Particularly effective protection of wood is achieved by large-scale industrial impregnation processes, for example vacuum, double-vacuum or pressure processes.

If appropriate, the ready-to-use compositions can additionally comprise other insecticides and, if appropriate, additionally one or more fungicides.

Suitable additional components which may be admixed are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in that document are expressly incorporated into the present application by reference.

Very particularly preferred components which may be admixed are insecticides, such as chlorpyriphos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron and triflumuron, and fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, dichlorofluanide, tolylfluanide, 3-iodo-2-propinyl-butyl carbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.

Example (I-b-1) ##STR47##

6.4 g (20 mmol) of 6-tert-butyl-5-chloro-4-hydroxy-3-(2,4,6-trimethylphenyl)-2-pyrone (Ex. I-a-4) are initially charged in 50 ml of ethyl acetate. At 20° C., 2.02 g (20 mmol) of triethylamine are added, and at 0° C. a solution of 1.6 g (20 mmol) of acetyl chloride in 20 ml of ethyl acetate is added dropwise. The mixture is subsequently stirred at 20° C. for 20 h. Precipitated triethylamine hydrochloride is filtered off with suction and washed with ethyl acetate. The combined mother liquors are washed twice with 50 ml of half-concentrated sodium chloride solution each time, dried over magnesium sulphate and concentrated under reduced pressure. 7.2 g of crude product are obtained. Flash chromatography over silica gel 60 (35-70 μm) using toluene:acetone 30:1 as eluent yields 4.1 g (57% of theory) of 4-acetyloxy-6-tert-butyl-5-chloro-(2,4,6-trimethylphenyl)-2-pyrone of melting point 116-118° C.

Similarly to Example (I-b-1) and/or according to the general preparation instructions, the compounds of the formula (I-b) listed in Tables 2 and 2a below were obtained.

Example (I-c-1) ##STR60##

3.8 g (10 mmol) of 5-chloro-6-(4-chlorophenyl)-4-hydroxy-3-(2,4,6-trimethylphenyl)-2-pyrone (Example I-a-1) are initially charged in 25 ml of ethyl acetate. At 20° C., 1.0 g (10 mmol) of triethylamine are added and a solution of 0.95 g (10 mmol) of methyl chloroformate in 10 ml of ethyl acetate is added dropwise at 0° C. The mixture is subsequently stirred at 20° C. for 20 h. Precipitated triethylamine hydrochloride is filtered off with suction and washed with ethyl acetate. The combined mother liquors are washed twice with 50 ml of half-concentrated sodium chloride solution each time, dried over magnesium sulphate and concentrated under reduced pressure. 4.0 g (92.4% of theory) of crude 5-chloro-6-(4-chlorophenyl)-4-methoxycarbonyloxy-(2,4,6-trimethylphenyl)-2-pyrone are obtained. Recrystallization from 50 ml of cyclohexane affords 3.1 g (72% of theory) of pure product which melts at 136-138° C.

Similarly to Example (I-c-1) and/or according to the general preparation instructions, the compounds of the formula (I-c) listed in Table 3 below were obtained.

To produce a suitable active compound preparation, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

Cabbage leaves (Brassica oleracea) are treated by being dipped into the active compound preparation of the desired concentration and populated with larvae of the mustard beetle (Phaedon cochleariae) while the leaves are still moist.

After the desired period of time, the plants are populated with larvae of the mustard beetle (Phaedon cochleariae). After in each case 3 days, the kill in % is determined. 100% means that all beetle larvae have been killed; 0% means that none of the beetle larvae have been killed.

In this test, for example the compounds of Preparation Examples I-a-1, I-a-2, I-a-4, I-b-1, I-b-2, I-b-7, I-b-8, I-c-1 and I-c-6 exhibited, at an exemplary active compound concentration of 0.01%, a kill of 100% after 7 days.

To produce a suitable formulation, 3 parts by weight of active compound are mixed with 7 parts of the abovementioned solvent-emulsifier mixture, and the resulting emulsion concentrate is diluted with water to the respective desired concentration.

2 ml of this active compound preparation are pipetted onto filter paper dishes (φ 9.5 cm) situated in Petri dishes of corresponding size. After the filter discs have dried, 25 test animals are transferred into the Petri dishes and covered.

The activity of the active compound preparation is determined after 1, 3, 5 and 24 hours. 100% means that all the flies have been killed; 0% means that none of the flies have been killed.

To produce a suitable formulation, 3 parts by weight of active compound are mixed with 7 parts of the abovementioned solvent-emulsifier mixture, and the resulting emulsion concentrate is diluted with water to the respective desired concentration.

For each individual concentration, 30 to 50 larvae are introduced into a test tube which contains 1 cm³ of horsemeat. 500 μl of the dilution to be tested are pipetted onto this horsemeat. The test tubes are placed in plastic beakers whose bottom is covered with sea sand, and kept in an air-conditioned room (26° C.±1.5° C., 70%±10% relative humidity). The activity is examined (larvicidal action) after 24 hours and again after 48 hours. After emergence of the larvae (about 72 h), the test tubes are removed and perforated plastic lids are fitted onto the beakers. After 1.5 times the development time (hatching of the control flies), the hatched flies and the pupae/cocoons are counted.

The activity criterion is the incidence of death in the treated larvae after 48 h (larvicidal effect), or the inhibition of the hatching of adults from the pupae or the inhibition of pupae formation. The criterion for the in vitro activity of a substance is the inhibition of the development of the fleas, or a development standstill before the adult stage. 100% larvicidal action means that all the larvae have been killed after 48 hours. 100% development-inhibitory action means that no adult flies have hatched.

In this test, for example the compounds of Preparation Examples I-a-2, I-a-3, I-c-4, I-b-2 and I-c-5 exhibited, at an exemplary active compound concentration of 1000 ppm, an activity of 100%.
